As you can see, I have two radios, one LTE and one 1x, same as on my last few phones. When I make a call though, the LTE is not available for data services, and 1x doesn't even show as a data option when voice is active. I cannot activate advanced calling because I'm not technically with Verizon. Is the problem that the calls are defaulting to the LTE radio? I've tried disabling volte in the network settings and it doesn't do anything.
Suggestions?

So, as some of you know, if you use the XT1060 with T-Mobile and connect to LTE, you'll have one of two issues: 1) it connects to LTE, but you can no longer call out (or receive calls) as the phone falls back to CDMA even when locked out in the network settings, or 2) it doesn't connect to LTE because it locks the T-Mobile 3G APN in even when a manual entry T-Mobile LTE APN is selected (my issue). My X absolutely REFUSED to move to fast.t-mobile.com and failed to connect to LTE and had absolutely no signal whatsoever (no HSPA or GSM even when on LTE/GSM/UMTS). The reason from the tower: APNfailed. Tried a million times to change the APN in the LTE area to no avail.
I've found it will only change to fast.t-mobile.com (manually entered) in a non-LTE area. Well that's a great inconvenience. I had to disable LTE completely and restart the phone to get it back on HSPA+ (or wait 5-10 minutes).
Anyway, the Verizon rep called me to "troubleshoot" my issues when connecting to T-Mobile LTE. I refused to go through the typical troubleshooting steps because none of it worked when I tried, so it's not magically going to change. I found that interesting (that they'd call me) even though I've had no direct contact with Verizon. Anyway, nothing was really resolved.
Both of these issues are violations of the C-block agreement. Also, if you select Global mode, it'll default to EDGE even though HSPA is available. It'll go to HSPA after selecting LTE/GSM/UMTS, UMTS only, then move back to Global. Interesting how they make you go through these hoops, eh?

Wow. Hopefully something changes with Verizon and letting people use LTE on other carriers. I know almost all Verizon phones don't get LTE on any carrier other than Verizon even if the LTE bands are supported. Verizon is full of crap.
In device info I find several options for the network mode: lte/gsm, lte/cdma, or lte only, but I want something like lte preferred. If I switch it on lte only, phone calls or sms stops working (can't receive or send). Is there anything I can try to prefer lte all the time? My Vodafone carrier in Romania doesn't support VoLTE and whenever I make a phone call it goes to 2g, then it takes a few seconds to switch to "H", but it almost never goes directly to 4g. I'm also rooted so some exposed module or something similar would also be appreciated.
Basically what I'm looking for is to prioritize lte all the time, but switch to 2g/3g when I make a phone call or there is no 4g signal. Can anyone help me out pls?
So maybe this was a bad idea but I'm on boom mobile (verizon mvno) and thought I could save some money and picked up a sprint s7 edge on sale, I just had it unlocked and they flashed it to the 935u unlocked version. The problem is I can't connect to the verizon network, after playing around with it a bit I got it to connect to the verizon lte network but still no voice. In my meager attempts to troubleshoot I noticed I have the options under network mode of
LTE/3g/2g -->> this picks up all networks in my area (Verizon, Sprint, ATT, Tmobile, US Cellular)
3g/2g --> only shows ATT and Tmobile
3g --> only shows ATT and Tmobile
2g --> only Tmobile
So I'm thinking my phone isn't setup right to connect to cdma networks which I thought the 935u rom was supposed to do. Anyone have any tips on how i can further troubleshoot this?
Thanks in advance.
edit: Well I installed a program called 4g LTE switch and set it to cdma only and I was able to make a phone call (3g data also worked) like that but changing it to LTE/cdma wouldn't let me make a call but LTE data worked, if i leave it set to LTE/cdma and reboot it switches back to LTE only.
edit2: Maybe it's trying to connect to volte which isn't offered for Verizon MVNO's yet but i don't see any settings available to disable that.
edit3: When set to LTE/CDMA I could sometimes make outgoing calls, sometimes I would get the double dial prompt, it was very slow to switch between LTE and CDMA so I would miss incoming phone calls.
I threw in the towel and just flashed the latest Verizon rom and it's working properly.
I have recently bought the MI A1. While buying itself it was updated to the latest may patch.
The problem is while on 4g network, I cannot receive nor make any phone calls. For calling I have to manually switch to 3g/2g mode from *#*#4636#*#* menu. Is this a normal behavior of this phone as my other phone swiches to 3g while incoming/ outgoing calls and back switches to 4g after the call is finished.
PS: my network doesn't support volte. Phone is manufactured on Feb 2018, it's not modified by any means.
That's not normal behavior.
I've never seen a phone where You have to switch between 3G/4G/LTE for calls and data.
Can You try a SIM-card from another service provider to see if it behaves differently?
If You check at https://willmyphonework.net/ are all bands supported with Your provider?
Or, in worst case of course, try a factory reset and see if that makes any difference...
Set to 3g/4g in *#*#4636#*#* menu.
Airtel doesn't support volte in all circles yet. Only rolled in few circles. In 3g/4g mode, it'll be mostly in 4g mode if nw strength is good & switch to 3g when you call or receive a call
So I use my sim on roaming and I have been facing this problem that my calls only work when I set mobile network to WCDMA or lower which hence reduces my data speed coz it's 3g. What to do?
4G (LTE) services is a data-only service, and does not support voice (unless it is voice converted to 4G data or VoLTE), hence whenever you're dialling or receiving a call network drops from 4G to 3G. Happens to me all the time on roaming, sometimes even on home network with poor VoLTE connectivity. Nothing to worry about.
